CAMRT Radiography Practice Exam

The primary use of an Endoscopic Retrograde Cholangiopancreatography (ERCP) is to investigate the biliary tree, common bile duct (CBD), gallbladder, and pancreas. This procedure combines endoscopy and fluoroscopy to visualize these structures, allowing clinicians to diagnose conditions such as bile duct obstructions, pancreatitis, and gallbladder diseases. ERCP is particularly valuable for identifying issues that may not be evident through non-invasive imaging techniques like ultrasound or CT scans.

While there are therapeutic aspects to ERCP, such as the removal of gallstones or the placement of stents in cases of obstruction, the fundamental purpose revolves around diagnostic investigation. Thus, the choice highlighting the investigative role of ERCP accurately reflects its primary intent in clinical practice.
